How should I read a head-to-head average built from only a few available meetings?
Read a head-to-head average with the number of verified meetings, the selected metric and unit, and the historical window. If only a few meetings are available, the average is based on only those observations; it does not become a stable or predictive estimate just because it is written as one number. If the query asks for the five most recent meetings but only a smaller sample is verified, state that smaller sample and whether older coverage is incomplete. Do not imply a complete history when only a few records were captured.

Put the sample size beside the average
An average hides how many observations contributed to it. State the metric, unit, participant, meeting dates or window, and sample size. With one meeting, the average is just that single observed value; with a few meetings, each observation can have a large effect on the summary.
- Report the number of verified meetings actually used.
- Distinguish a smaller available sample from a complete five-meeting search.
- Keep unavailable older meetings separate from a verified absence of meetings.
A small average is not a precise estimate
A single average does not show the spread across meetings or whether the same pattern held each time. Avoid words such as typical, reliable, or expected unless separate evidence supports them. The average describes only the selected historical observations.
Tell the reader what could not be verified
If older records are missing, name the coverage limit and the period you actually searched. Do not quietly treat missing meetings as zero-value observations or claim that the available meetings are the full history. A historical average is not a prediction for a future matchup.
Hypothetical example: two meetings do not equal five
Imagine a synthetic request for the five most recent verified direct meetings, but only two records are confirmed in the captured source: 4 and 10 generic units for the selected metric. Their arithmetic average is 7 units across n=2. Report that exact sample and window; do not label it a five-meeting average or say the older three values were zero. These invented values are not a real head-to-head record or a forecast.

If I have only one verified meeting, can I still report an average?
You can report the single observed value with n=1, but label it as one meeting rather than presenting it as a broad or predictive average.
